Model the reflection of a light wave.
1.
Choose a material that will reflect light.
2.
Create a diagram that represents a light wave being reflected.
3. Label your diagram "Light Wave Reflected."
4. Below the diagram, write a brief description of the interaction between the wave and the
material. Be sure to discuss the angle of incidence, the angle of reflection and the normal.
Also explain how the amplitude and frequency of the wave are affected.
When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.
What is Light wave?The simplest instance of visible light reflection is a smooth pool of water's surface, where incident light is orderedly reflected to provide a clear image of the landscape around the pool.
When you throw a rock into a pool, it disturbs the water and causes waves, which prevent reflection by spreading the light rays in all directions.
The incoming light wave is referred to as an incident wave, and the wave that is bounced away from the surface is termed the reflected wave. Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth.
Therefore, When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.

A post- doctorate position is most likely to be held by Oa geriatric allergist an allergist a pediatric immunologist. A scientific research immunologist .
Answer:
A scientific research immunologist
Explanation:
A postdoctoral (commonly called postdoc) position is a temporary working position assigned by a particular institution/government agency to investigate questions referred to a particular research field/discipline (e.g., economy, molecular biology, immunology, politics, etc). In general, a postdoc is a 2-year position obtained after Ph.D. (i.e., Doctor of Philosophy) completion. This short-term research position is useful for professionals who require further training in a particular field/discipline, giving the individual more independence than in a Ph.D., which allows the development of technical skills and increases his/her interest in a particular research area.

As the nutritional energy passes through the food chain, energy......
O a) is gained
b) decreases
c) remains constant
d) increases, then decreases
Answer:
B. Decreases
Explanation:
In an ideal food chain, nutritional energy from producers (plants) are transfered to other animals at different levels on the food chain. As nutritional level is being passed from one level to another, most of the nutritional energy is lost in the process. Therefore, energy decreases as the nutritional energy passes through the food chain.

Making stuff with mud is science because these are experiments used to establish facts and principles about mud and/or the different types of soil constituting the mud
Explanation:
Science is a discipline that studies the establishment of facts, principles and methods through experimentation and instills processes of investigations to learners. Making stuff with mud can be used to establish facts and principles e.g clay soil has smooth and fine particles and has high adhesive forces of attraction with water and hence will make longer and thinner ribbons while sand has large rough particles which make large and chubby (I couldn't think of another word) ribbons due to the weak adhesive forces between the particles and water.
